Wondering what ammo to use in my RB 454, against bears. Black or Brown since I won't be reloading depending on the color. I read a post a while back about using 260 grain XTP hollowpoints for black bear since they would stop attacking and try to get out the "Burning Bee" giving you a good follow up shot. I was thinking more along the lines of Corbon 320 grain FP Penetrators or Buffalo Bore 300 grain J.F.N. so I could get maximum penetration. I do not handload so factory ammo have to work for now. I am new to Alaska and had to many times last summer/fall when I wish I was packing more than my pit bull. Hope you fellows can educate me on what load I should be packing.
